The SPX2730/31/32/33 is a 3A high accuracy, low dropout voltage regulator (370mV(Typ)@ 3A). The SPX2730/31/32/33 is designed for low voltage application that requires lower dropout voltage and faster transient response. This device is an excellent choice for use in powering low voltage microprocessor that require a lower dropout, faster transient response to regulate from +2.5V to 3.8V supplies and as a post regulator for switching supplies applications. The SPX2730/31/32/33 offers full protection against over-current faults, reversed input polarity, reversed load insertion, and positive and negative transient voltage. On-Chip trimming adjusts the reference voltage to 1%. Features such as enable pin, Error flag pin are also included in the 5-pin package. The SPX2730/31/32/33 are offered in 3 & 5 pin TO-220 & TO-263 packages compatible with other 3 terminal regulators.
